I did exactly as you said and then instead of R-click used the drop-down menu and it does the same.

removed ALL 660 reference, rebooted, still there.

Brought UP Control Panel PRINTERS - Removed HP-660 (gone) closed window, brought it back UP and there it was back again.

Did it again uninstalled, rebooted, brought up PRINTERS and it was back there.

CANNOT remove it ANY way.

Very frustrating.

i can remove any and all other programs which works EXCEPT printer.

Never had this problem until I let someone from HP (in India) remotely access my computer and at some point he installed a 6800 printer but no reference to that. Ever since he did that all my installations have the long name........ HP-6600 (copy 1)
